網上各種教程用的方法主要是如下這一句：

QAxObject * range = worksheet->querySubObject("Cells(int,int)", 1, 1 );

　　核心程式碼在於這一句：

QAxObject *range = worksheet->querySubObject("Range(QString)", "B13:C1000");
 

　　附上完整的原始碼供大家交流學習：

　　pro中加一句：QT+=axcontainer

　　標頭檔案加一個：#include <QAxObject>

　　核心程式碼：

// 批量讀取xls到map
int readEnvXlsFile(QString FileName, QMap<QString,float> &map)
{
    QAxObject *excel = NULL;
    QAxObject *workbooks = NULL;
    QAxObject *workbook = NULL;
    excel = new QAxObject("Excel.Application");
    if (!excel)
    {
        qDebug() << "EXCEL物件丟失!";
    }
    excel->dynamicCall("SetVisible(bool)", false);
    workbooks = excel->querySubObject("WorkBooks");
    workbook = workbooks->querySubObject("Open(QString, QVariant)", FileName);
    QAxObject * worksheet = workbook->querySubObject("WorkSheets(int)", 1);//開啟第一個sheet
    QAxObject * usedrange = worksheet->querySubObject("UsedRange");//獲取該sheet的使用範圍物件
    QAxObject * rows = usedrange->querySubObject("Rows");
    QAxObject * columns = usedrange->querySubObject("Columns");
    int intRows = rows->property("Count").toInt();
    int intCols = columns->property("Count").toInt();
    qDebug() << "xls行數："<<intRows;
    qDebug() << "xls列數："<<intCols;

    // 批量載入資料，這裡預設讀取B13:C最後
    QString Range = "B13:C" +QString::number(intRows);
    QAxObject *allEnvData = worksheet->querySubObject("Range(QString)", Range);
    QVariant allEnvDataQVariant = allEnvData->property("Value");
    QVariantList allEnvDataList = allEnvDataQVariant.toList();

    for(int i=0; i<= intRows-13; i++)
    {
        QVariantList allEnvDataList_i =  allEnvDataList[i].toList() ;
        //qDebug()<< allEnvDataList_i[0].toString()<< allEnvDataList_i[1].toFloat();
        map.insert(allEnvDataList_i[0].toString(),allEnvDataList_i[1].toFloat());
    }
    workbooks->dynamicCall("Close()");
    return 0;
}
